My friend, I am in complete agreement about variation, and changes on climate. That is common. I'll try to find you a great JRE where a guest cites multiple excellent historical examples of decades long increases and declines in global temp since the dark ages.

The company earlier this month announced it would add Google Assistant support to the Nest Secure system, meaning owners would have the ability to deliver voice commands to control the system. The announcement immediately raised questions because it meant Google was allowing users to activate a built-in microphone that customers previously did not know existed.

"The on-device microphone was never intended to be a secret and should have been listed in the tech specs," a Google spokesperson said in a statement on Wednesday. "That was an error on our part."
